In universal Darwinism, copying is found ubiquitously in nature, from spreading ripples to propagating cracks, from growing crystals to scattering radiation. Of course, copying, variation and selection are the basis of Darwinian evolutionary theory. The copying takes a variety of forms, but the most basic is positional inheritance - the topic of this post.
It is common knowledge that people inherit the environment of their parents - along with their parents genes. They inherit the local climate, the local language, government and religion - along with traits coded in DNA. These are examples of positional inheritance.
Many other organisms lack good dispersal strategies and exhibit the same kind of effect. Rabbits tend to inherit the warren of their parents. Corals inherit their parent's reef - and so on. Much the same is true of many inorganic natural forms. For example:
Splitting raindrops - produce offspring that inherit their parent's position.
Propagating cracks - when a crack tip divides the offspring crack tips start their lives nearby.
Nuclear decay - when atoms split, the offspring particles originate near the parent atom.
Because of multiverse locality, any form of inheritance is also accompanied by positional inheritance. That makes positional inheritance the most widespread form of inheritance in existence.
Since positional inheritance is so fundamental, how come you have never heard of it before? How come searching for the term just turns up this page? Well, there are some "nearby" terms, which have received more attention historically. Ecological inheritance, environmental inheritance and niche inheritance. These terms are fine - but they simply don't mean the same thing as positional inheritance. Positional inheritance is the inheritance of spatial position. That often comes with a bunch of other things as well - but not necessarily.
This book has a title which is obviously based on Charles Darwin's 1859 book. It's about the author's discovery of cultural evolution and memetics. The author imitates Darwin's trip to the Galapagos by seeking out cultural islands within the American mainland - mainly looking at artefacts - hats, barns and tepees. It is an unusual mixture of popular science and road trip.
The author uses the metaphor of view-point-altering googgles to help describe his journey. When he puts the goggles on he looks at things through the eyes of a cultural evolutionist - and the world looks pretty different and unusual to him.
The memetics in this book is good. Jonnie Hughes has a pretty good understanding of the topic, in
my opinion.
The author spends most of the book on cultural evolution, and then describes how the "gene" revolution - which transformed evolutionary biology in the 1950s and 1960s - has a direct parallel in cultural evolution - which has its own little bits of inherited cultural information: memes. This insight has led to the "meme's eye view" - and other important developments.
If I made scientific criticisms, I would first point to the author's endorsement of internalism, which I find to be an unhelpful perspective. The other thing that I thought was wrong was his explanation for why memes have not made much progress in academia. He says it is the difficulty in actually identifying them in the brain. That isn't really the right answer. Plenty of other things that can't be directly observed don't face the same problem. There are several other reasons why academia has had trouble digesting memetics.
Much of the serious science in the book is confined to a bibliography at the end. It is four pages long. I would have preferred the whole book to have been like that. Memetics needs the attention of scientists more than it needs conversion stories by science writers.
Lastly I'll tell you about my favourite bit of the book. It's a bit near the end - where the author likens pioneer species colonising a new environment to memes colonising an infant's mind. Hughes explains in some detail how the early species in an environment create the ecosystem for those that follow them - in the same way that early memes create a mental environment for the more complex ones that follow them. This is a beautiful analogy, and in the hands of an eloquent science writer like Hughes, it is a joy to read.
Let's hope Jonnie keeps those memes coming in the future.
The Robot's Rebellion: Finding Meaning in the Age of Darwin - by Keith Stanovich.
The book is a manifesto expanding on Richard Dawkins' idea at the end of The Selfish Gene. Dawkins wrote:
We have the power to defy the selfish genes of our birth and, if necessary, the selfish memes of our indoctrination. We can even discuss ways of deliberately cultivating and nurturing pure, disinterested altruism - something that has no place in nature, something that has never existed before in the whole history of the world. We are built as gene machines and cultured as meme machines, but we have the power to turn against our creators. We, alone on earth, can rebel against the tyranny of the selfish replicators.
Stanovich turns this into the central thesis of his book. His book is about a type of morality and ethics which is informed by evolutionary theory.
Stanovich comes from a long line of thinkers that views nature as immoral, or at best amoral. Thomas Henry Huxley, Richard Dawkins, Daniel Dennett and many other thinkers have painted nature as curel and indifferent - and evolution as bad and not to be imitated.
Stanovich - like Dawkins - proposes that humans rebel against selfish replicators - namely genes and memes - and instead promote their own interests: "the interests of the vehicle", as Stanovich calls them.
Most of the book is about why and how humans should rebel against their genes. He pictures humans as part-conscious and part-unconscious systems. He sides with the conscious component, or the ego, and characterises our unconscious minds as sub-human saboteurs, getting us to do things that make us miserable against our own best interests.
The whole topic is an interesting one, though the book is a bit on the dry and repetitive.
The book has a section on memes, which is quite good. Stanovich recognises memes as forming a second evolutionary system, and has a pretty good understanding of memetics. However, memes are just another type of selfish replicator to Stanovich. They no more have our interests at heart than our genes do. Indeed, he characterises many memes as being especially nasty - "nastier than genes even", as he puts it.
In the rest of this review, I will directly address Stanovich's main thesis. I should say at this point that I am not sympathetic towards it. The idea that evolution is bad has been opposed by thinkers such as Julian Huxley and Peter Kropotkin. Like them, I see in evolution's positive, cooperative side a guide about how to behave. The views of Huxley and Kropotkin have been mostly trampled on by subsequent thinkers, but their ideas about evolution and cooperation are essentially correct - even though they are not currently in vogue.
The idea of enlightened humans rebelling against the interests of sub-human replicating agents is an intriguing one, but I don't think it is founded in good science. The problem is that Stanovich's picture doesn't include all the copying processes that are taking place.
While Stanovich deserves credit for recognising both DNA genes and memes, he doesn't treat within-brain change as an evolutionary process. However the fact that individual learning also forms its own evolutionary process was recognised long ago by Skinner, Campbell, Calvin, Cziko, Dennett and others. Indeed, any non-trivial goal-directed system is going to have a fitness function and an evolutionary tree-pruning algorithm at its heart.
In rejecting genes and memes, Stanovich is just throwing has hat in with other evolving structures within the brain. Stanovich claims to be siding with "the vehicle", but, in practice this turns out to be something close to the ego, which itself is composed of a bunch of happiness-promoting replicating structures that Stanovich didn't consider. In short, all positions to this topic involve siding with some bunch of copying entities or other. Copying with variation and selection underlies every optimisation process. The issue is not whether to side with a bunch of copied entities, but rather which ones you side with. With this framing of the problem, much of Stanovich's rhetoric about the inhumanity of stupid mindless replicators falls flat.
There are indeed some reasons follow the dictates of your conscious mind - that part of you is often smart and forward thinking. However, the brain's analytic side is heavily dominated by the ego - which is rather like the brain's public relations department. A big part of its job is to convince everyone else how wonderful you are. Stanovich's proposal is rather like giving control over a company to its public relations department. Egoism is fairly common, but there's more to a human than their ego. Thinking of yourself as being your ego is an impoverished picture of yourself which ignores much of what makes you human. Egoism is partly a western disorder - those from non-western cultures are less likely to identify completely with their egos. So: I think Stanovich's idea takes things too far.
Since the ego is largely constructed by genes, we can expect most humans to not have rebellious egos - since those with a tendency to rebel against their genes would have left behind fewer children. So, one wonders what fraction of humanity Stanovich is preaching to.
Stanovich proposes redefining the word "rationality" to refer to actions that promote the interest of "the vehicle". This plan strikes me as being a hopeless one - that just isn't what the word "rationality" means. I think that idea that rationality consists of optimising the function that Stanovich recommends is a non-starter.
Stanovich's book can be regarded as an interesting example of an attempt at founding a secular religion based on science. Stanovich's memes do get cited from time to time and have found themselves an audience. There's a type of human that hopes that their ego will live forever - and isn't interested in reproducing - and some of them seem to approve of Stanovich's ideas.
However, my council is to consider Stanovich's book as another memeplex that wants you to divert your resources into propagating it - at the expense of your own genetic heritage. There are a lot of memes out there hoping that you will divert some of your reproductive resources towards their propagation. Stanovich promises you happiness - if you are prepared to get off the genetic train and - consign your genes to eternal oblivion. If you are normally OK with memes hijacking the goals that nature gave you, then, by all means, go for it. However, if you don't usually approve of that, then I recommend being as cautious of embracing Stanovich's memes as you are of any other ones.
The Origin of Everything via Universal Selection, or the Preservation of Favored Systems in Contention for Existence
...by D. B. Kelley. The book is clearly named after Darwin's 1859 book titled:
On the Origin of Species by Means of Natural Selection, or the Preservation of Favored Races in the Struggle for Life
My book is a review copy - which was sent to me ahead of its release by its publishers. The main topic is universal selection - and what an important idea it is. I'm pretty much on board with the author's views regarding the high level of significance of the topic. Universal Darwinism is a tremendously important subject - and universal selection is a big part of it.
Many people who are interested in expanding the domain of Darwinism only extend the theory to cover the social sciences, the brain and development - leaving the idea still confined to the life sciences. By contrast, this book extends the idea of selection far beyond the social sciences - emphasizing that selection applies to practically everything - including natural selection of moons, stars, atoms, galaxies, chemical compounds and all manner of other things. I think this emphasis is correct - Darwinism and natural selection do also cover the inorganic realm.
Some apply selectionist ideas to complex adaptive systems, but the author points out that even atoms qualify as being complex - and so pretty much any system you care to think of qualifies as a complex system. The author prefers to just call them "systems". I think this is a helpful perspective.
The book offers a symbiosis-friendly version of Darwinism - extending mutualism and parasitism into the organic realm as well. I think that makes reasonable sense - though some will probably view it as being a step too far.
The author presents selectionism as a part of physics. However, since it also applies in a wide range of universes with different physical laws - such as Conway's Game of Life - I prefer to think of it as a principle of statistics - broadly similar to statistical mechanics.
The book offers a treatment of universal selection and the anthropic principle. It's the best treatment of this topic that I have encountered. There is a discussion of memetics, although it is pretty small section. The book also discusses selectionism as a grand unifying principle in science, and the scale of its possible impact.
However, this is a book with a number of problems - some of which I will now describe:
The book is quite repetitive, making essentially the same point regarding the ubiquity of selection over and over again.
There's a lot of discussion of selection, but not much breaking this down into copying and destruction. Copying and destruction are very different ideas, which demand independent treatment and analysis. Bundling them together into the single category of "selection" doesn't really do either of them justice.
The author doesn't really distinguish much between cumulative adaptive evolution and degenerative evolution. This is a pretty critical distinction if extending Darwinism into the inorganic domain.
Other principles - besides universal Darwinism purport to explain the evolution of complex adaptive systems. In particular maximum entropy thermodynamics purports to explain the evolution of a wide range of living and non-living systems. Those discussing universal Darwinism need to discuss the relationship between it and existing ideas like these - but the author doesn't really do that. There is a chapter on entropy - but that addresses quite a different topic.
There's quite a lot of discussion regarding links between Darwinism and relativity in the book. I think this link is overstated.
The author seems to think the material in the book is quite original. However, I wasn't really convinced of that. I published an essay titled "Universal Selection" online in 2010 - which fairly plainly and clearly extended selection into the inorganic domain. I didn't come up with the idea either - my essay cites a paper from 1996 on essentially the same topic.
Radical extensions of Darwinism can expect to face criticism. For example, Massimo Pigliucci says:
Physicists talk about the evolution of the universe all the time but all they mean by that is: change over time. Now, if that is what we mean by "evolution", then pretty much everything falls under evolution - so surely we must mean something more specific than that.
I think those writing in the area should make an effort to anticipate and address such criticisms. However, this book doesn't seem to be written with critics in mind - rather it is a book of enthusiastic advocacy of the idea. I also think that those working on radical reformulations reformulations of Darwinism should probably take efforts to appear credible. The author could have taken more steps in that direction. For one thing, I spotted a number of mistakes. For example, the book claims that trees are asexual. It claims that monkeys and dinosaurs coexisted. It repeatedly reports a discovery of faster than light travel, which was subsequently widely discredited. These kinds of things don't make a positive contribution to making the case.
So, to summarise, this is a good and important book, but it also suffers from a number of flaws. However, because of the vaccuum in the area, any contributions to it are very welcome - and consequently this book makes essential reading for anyone interested in the issue of the domain of Darwinian theory.
Hi! I'm Tim Tyler, this is a review of this book: Universal Darwinism - by John Campbell
This is one of a tiny number of books on the tremendously important - yet dreadfully neglected - topic of Universal Darwinism. The extension of evolutionary theory into fields beyond the realm of organic biology is long overdue.
The book adopts a perspective based on information theory - and makes many links to the concept of Bayesian updating. It suggests that knowledge acquisition by brains and the accumulation of survival know-how by evolution are closely related. This aspect of the book is excellent.
The book takes a rather conservative approach to Universal Darwinism - sticking to those cases with the best literature support. This conservatism has a positive side - in that critics will find fewer flaws in the book. However, it means that there is little discussion of Darwinism in prebiotic systems - such as whirlpools, crystal growth, propagating cracks and turbulence. Nor is there much discussion of the law of "survival of the stable", or natural selection on a cosmic scale - though Smolin's ideas do get a few lines.
The author correctly links Universal Darwinism to maximum entropy thermodynamics. This is a real and important link - but the author's treatment of the maximum entropy idea is very cursory: he just treats maximum entropy as a constraint. Universal Darwinism and maximum entropy thermodynamics are deeply-linked ideas, but although this book has a whole chapter on the topic, it doesn't really go into their relationship very much.
The book deals with four main examples of Universal Darwinism: quantum physics, biology, learning and human culture. The 'biology' section seemed rather unnecessary to me - application of Darwinism there is well known and this topic has been treated by many others. The sections about cultural evolution and brain evolution are both good. For me, it was also nice to see material about memetics in the book. Lastly, there is a large section about "Quantum Darwinism". Quantum physics doesn't make a great example to illustrate Universal Darwinism with simply because quantum physics is so difficult to understand. I didn't really get on with the author's presentation, because it was framed in terms of "wave function collapse" - a proposed physical process which, so far, we have yet to find any evidence for. A presentation that is more agnostic about its interpretation of quantum physics would probably have a smaller chance of alienating the reader.
I thought that probably the biggest problem with the book is what it omits. Application of Darwinism to complex adaptive systems is a large and important subject. It is also much easier to understand than quantum physics. I wasn't convinced that the author understood this aspect of the topic very well - otherwise, surely it would have been included.
So, overall, this is a very welcome contribution to the topic, but I think it leaves considerable scope for further light to be thrown on the subject.
One problem for evolutionary theorists interested in human behaviour is that the field is littered with the corpses of dead and discredited theories.
Social Darwinism - has now become a synonym for evolution-inspired racism and eugenics programs and supposedly-discredited unilinear evolutionary theories.
Sociobiology - both the memetics and cultural evolution were born in a revolution against Wilson's sociobiology - whose reduction of everything to genetics was half-baked.
Evolutionary psychology - this has turned out to be the study of human universals. That is a travesty of a genuine evolutionary study of human psychology.
Behaviourism - the study of behaviour, or so you might think. Alas, what went wrong?
The problem is that these theories have sensible-sounding names, which now can hardly be used, due to their pollution with the bad ideas from the past.
Evolutionary psychologyshould be the study of psychology from an evolutionary perspective - including the evolution of individually and socially learned ideas - instead of the current mess.
Social Darwinismshould be the study of the evolution of societies from a Darwinian perspective - obviously an important field.
Sociobiologyshould be the study of social behaviour in biology - and not refer to Wilson's ideas on the topic, which didn't always make a lot of sense.
Behaviourismshould be the study of behaviour. Alas, to most people it refers to a discredited theory today.
We can probably rescue these words from the dustbin of history - but only if we make an effort to start using them to mean what they ought to mean.
The expansion of the domain of Darwinism to the human sciences is the biggest and most significant scientific revolution I have ever lived through. However, I am disappointed with the slow progress of the revolution. There's a lot of tenures on the line, and it seems as though some are prepared to fight every step of the way, and others who don't want disruption. As a result, progress is frustratingly slow.
So far, I've mainly focussed on memetics - which seems to be the most important domain in terms of applications. Next-most important is probably the field of within-brain evolution. However, for a while I've been aware that Darwinism has a much broader domain of application, going beyond the organic sciences into inorganic realms: turbulence, cracks, erosion, fires, crystals, radiation, etc.
After my next "memes" book, I will probably focus some of my energy on explaining and promoting Universal Darwinism. Universal Darwinism is relatively simple and easy to understand. The field is so badly neglected that a shock-and-awe campaign in the area could easily result in big gains in understanding.
While the inorganic sciences may lack human impact, more widespread acceptance of Darwinism's broader base would imply the correctness of memetic and brain within-brain evolution as sub-fields.
